why is there one hour gap between blocks that are mined?

[pooya87]

the new blocks are supposed to be mined every 10 minutes but sometimes i see shorter or longer time between blocks but right now the last block was mined about an hour ago?

what is up?

EDIT:

can anyone explain why this happened?

[korila]

after an hour now it has just mined 1 block . omfg

[Digital_Lord]

A New block just mined 2 minutes before. and previous block was mined 5 minutes before. only 3 minutes deference between them, seems now everything is working fine...
I am also wondering what happened with mining pools. why it stopped for almost one hour. why blocks are stopped for one hour..

yeah i edited my post to change the title so that it matches the current situation.

i don't know if this has happened before or not but i have never seen more than 20 min gap between blocks.

Sometimes too many fake transactions in network or too many ddos attempts, that's why it might take longer for a block to be found.

No that is not why at all. The time is random, but the average is about 10 minutes, Sometimes it takes 30 seconds. Sometimes it takes an hour.

[franky1]

the time is semi-random but based on the maths that the probability of 2016 blocks will be found over a two week period. and an adjustment of the difficulty to make it easier to make 2016 blocks over 2 weeks or harder to make 2016 blocks over 2 weeks.

no where in the code does it state 10 minutes.(that is just a human calculation away from the code)

however the probability of 2016 blocks over 2weeks (statistically, human calculated but not in code) works out as 1 block per 10 minutes.
but when it comes to the code and the rules of mining.. the blocks can be made in a couple minutes or couple hours. but has a bit of difficulty tha doesnt make it totally random

its this difficulty variable that is adjusted to make it harder if more then 2016 blocks are made over 2 weeks. or adjusted to make it easier if less then 2016 blocks are made over 2 weeks

again no where in the code does it state a block is made in 10 minutes.. instead its 2016 blocks over a 2 week period

This is disgraceful.

This "1 hour" block prop, or "1 miniute" block prop has always been, and will always be.
Now you noticed?

Clueless sig campaign hero BCT members, helping to destroy BCT credibility.

thanks you franky1 for the explanation.

if you think asking about a simple thing that i have never noticed before in the past two years in bitcoin destroys BCT credibility then you are clueless.

If it took you 2 years and 3000 posts to notice this most simple basic thing is happening and not understand why,
I think we can see who is clueless here.

1.  The ability to buy Hero an even Legendary accounts + signature campaigns for Hero and Legendary accounts = market for accounts + signature spam + noobs owning Hero accounts

2.  Hero accounts should be answering basic questions like this not asking them

3.  You are a noob that bought a Hero account just to spam your signature to make a profit

Have you made a profit on your purchased account yet?

Here you can find some useful function regarding exponential distribution. I've posted these images recently in another thread:




Read[1]:

There are lots of block intervals with a time less than 10 minutes but then a few block intervals much longer which bump up the average to 10 minutes. So the bitcoin network can get unlucky and a block won't be found for a whole hour.

These are extremely useful graphs to demonstrate that the AVERAGE block time is 10 minutes. By chance can take as long as it wants- 1 hour for 1 block is rare but it happens now and then by chance.

Yet another reason to increase the average block generation frequency.

[BurtW]

Yet another reason to increase the average block generation frequency.

No, it is not a reason to do anything.  It is a question about how Bitcoin works. 

Answer:  just fine, as designed, as expected, nothing new, long blocks happen at the expected frequency, nothing needs to be "fixed", Bitcoin has worked like this for years and will continue to work just fine, as is, for many more years.

If you want an increased block frequency use another coin.  There are plenty of them with a faster block time.

ok let me explain to you all what rank means on a forum:
it doesn't mean i am a bitcoin developer now, or have a complete knowledge or understanding of bitcoin and how it works,... and never claimed it either!
it only means that i have been Using bitcoin and bitcointalk for a long time.

and although i am interested in learning about the technical stuff about bitcoin and have also gathered some knowledge over the years i still don't know everything about bitcoin and there are still lots of things i don't know or misunderstood after i read things. which might sound to you as "basic"

and in the end i am mostly interested in using bitcoin not learning every single detail about it, i only know and am interested to know what seems important or interesting to know 

and just FYI, i own this account from 2014-9
